He has 700 more pics of you naked in addition to those 200? I doubt he just has them for his own pleasure. Typically one or two would be enough. My husband likes to have pics of me on his phone and I know he looks at them when he misses me: to clarify I am dressed in there and they aren’t taken in secret, just our vacation pictures or what not.

Hundreds of naked pictures and videos taken in secret aren’t for just persons own pleasure.

You better focus on your safety right now. Don’t destroy pictures but keep in a secret place. They might come handy in the court of law.
